Description

[Detailed Description of the Invention] The present invention relates to a partition plate used to drain or stop water in a channel in a ditch, such as a drainage ditch in a field or a temporary side ditch in a developed area.

Work to flow or stop water in the channel of a drainage ditch or temporary side gutter is carried out when the channel in the ditch is branched and it is necessary to direct water to the branched channel, or when it is necessary to stop the water in the branched channel. It will be done. Conventionally, this work was carried out by piling up embankment in the trench passage, which was inconvenient and time-consuming and required a great deal of labor. In addition, in areas where there is only sandy soil, water seeps in even if embankments are piled up, making it difficult to reliably stop the water. On the other hand, after the embankment is piled up and water is stopped, the embankment may be washed away by the water flow, and the work to remove the embankment is just as time-consuming and inconvenient as when the water is stopped. .

The present invention provides a partition plate that can be manufactured easily and inexpensively from synthetic resin, etc., can be quickly and easily attached to and detached from the channel in the groove, and can be reliably watertight. The aim is to eliminate the need for the traditional work of piling up embankments and removing embankments.

The partition plate illustrated in FIG. 1 includes a partition plate main body 1 and a pair of left and right engaging pieces 2 and 3 integrally provided at the upper end of the partition plate main body 1. Partition plate body 1
is composed of a synthetic resin plate having the same cross-sectional shape as the inside of the groove wall, which will be described later, and in the illustrated example, an elastic seal packing 4 made of rubber or soft synthetic resin is attached to the outer edge of the plate. has been done. This seal packing 4 is held in a fitted manner on the partition plate main body 1 as shown in FIG. A U-shaped one as shown in b, a U-shaped one as shown in c in the figure, and others are selected as required. Next, the pair of left and right engaging pieces 2 and 3 are attached to the partition plate main body 1.
is formed integrally with. As is clear from FIG. 1, one of the engaging pieces 2 has an inwardly open U-shape in which a pair of upper and lower horizontal parts 21 and 22 are integrated by a vertical part 23. An upward protrusion 24 is integrally provided at the end of the horizontal portion 22 on the side. Further, the other engagement piece 3 has a pair of upper and lower horizontal parts 31, 3, similar to the above-mentioned one engagement piece.
2. In addition to being provided with a vertical portion 33 and an upward protrusion 34, the guide portion 35 is provided that extends diagonally downward following the protrusion 34. Note that the other engaging piece 3 also has a U-shape with an open inner side.

Such a partition plate is attached to the groove wall 100 as shown in FIGS. 3 and 4, and the groove passage 20 is
Partition 0. The groove wall 100 to which the partition plate is attached is
As is clear from FIG. 3, it has a U-shape when viewed in cross section, and the left and right ears 110, 120 extend horizontally outward. These ears 110, 12
0 is provided for the purpose of increasing the rigidity of the groove wall 100 when it is molded from synthetic resin, etc., and its end is usually formed with a downwardly hanging protrusion 111, It is 121. When the partition plate is attached to the groove wall 100, the left and right ears 110, 120 of the groove wall 100
The left and right engaging pieces 2 and 3 of the partition plate are elastically engaged with each other, so that the seal packing 4 of the partition plate is brought into close contact with the inner surface 101 of the groove wall. That is, in the above state,
By elastically engaging one of the engagement pieces 2 with one of the ears 110 in a hugging manner, the engagement piece 2 is pressed downward by the protrusion 111 of the ear 110, and the other Similarly, the other engaging piece 3, which is elastically engaged with the ear portion 120 in a hugging manner, is also pressed downward by the protrusion 121 of the ear portion 120, and these pressing The seal packing 4 is brought into close contact with the inner surface 101 of the groove wall under the force. Further, as is clear from FIG. 4, in the above state, the engagement pieces 2 and
3 are engaged over a relatively long range, the partition plate does not tilt or wobble even if it receives the pressure of the water accumulated in the groove passage 200, and a reliable water stop state is maintained at all times.

When attaching the partition plate shown in FIG. 1 to the groove wall 100 as shown in FIGS. 3 and 4, it is convenient to follow the following procedure. That is, one engagement piece 2 is connected to the groove wall 1.
00, and the protrusion 111 of the ear 110 is inserted between the vertical portion 23 and the protrusion 24.
is locked, and from this state, the other engaging piece 3 is pushed into the other ear 120 of the groove wall 100. In this case, as shown by the imaginary line in FIG. 5, the guide part 35 comes into contact with the corner part of the ear part 120 in the first stage, and in the next stage, the engagement piece 3 and the ear part 120 are pressed against each other. Therefore, while both are elastically deformed, the engaging piece 3 is brought into contact with the ear part 1 through the drawing action of the guide part 35.
At the final stage, the protrusion 34 of the engagement piece 3 is fitted onto the outside of the protrusion 121 of the ear 120 due to the elastic restoring force of the engagement piece 3 and the ear 120.
1 and fit inside it, and the two engage as shown by the solid line in the figure.

In addition, when removing the partition plate, for example, by pulling the guide part 35 shown in FIG.
0, and then, while lifting the partition plate, remove one of the engaging pieces 2 shown in FIG. 3 from the ear portion 110. FIG. There is. That is, this is an example in which a pair of left and right seal packings 42 are bonded to necessary locations on the inner surface of the groove wall 101, for example, in the vicinity of the branch point when there is a branch path, using an adhesive. In this case, if the seal packing 42 is provided with a guide groove 421, the partition plate main body 1 can be inserted and removed through the guide groove 421, so there is an advantage that the partition plate can be reliably attached and removed at a predetermined position. The left and right engaging pieces 2 and 3 of the partition plate have the same configuration as explained in FIG. In the fitted state, the partition plate main body 1 is pressed against the seal packing 42 by the same action as that explained in FIG. 3, and reliable water stoppage is achieved.

In FIG. 6, the seal packing 42 bonded to the inner surface 101 of the groove wall protrudes into the groove passage 200, so when the groove passage 200 is opened, the seal packing 42 does not obstruct the smooth flow of water. There is a drawback that garbage etc. tend to accumulate easily. Therefore,
As shown in FIG. 7, the above-mentioned difficulty can be solved by forming a recessed groove 102 in the groove wall 100 and incorporating a seal packing 43 in the recessed groove 102.
In this case, as shown in FIG.
(See Fig. 6) If the guide groove 431 for inserting and extracting is formed only on the side surface of the seal packing 43, the guide groove 431 can sufficiently achieve the positioning of the partition plate and the water-stop function, but the guide groove 43
1 has the advantage that no dust etc. accumulates.

In the above embodiments, a seal packing is used for reliable water stoppage, but the seal packing is not necessarily necessary in the present invention. In other words, there is little need to strictly shut off water in drainage ditches in fields and temporary side ditches in developed areas, and some leakage is allowed. There is no need to use sealing pads in such locations. Further, if the above-mentioned partition plate main body is made of a rubber-like elastic body such as an elastomer, the same reliable water-stopping effect as when using a seal packing can be achieved without using a seal packing.

As is clear from the above, the partition plate according to the present invention not only eliminates the need to pile up and remove embankments when stopping or draining water into a channel in a trench. Water can be stopped or flushed simply by engaging and disengaging the engaging piece with the ear part of the groove wall, so that work can be done quickly and easily. Therefore, the quality of the surrounding soil does not become a problem, unlike when blocking water by piling up embankments. In addition, since the engaging piece is elastically engaged with the ear part of the groove wall, it can be securely attached to the groove wall, and therefore it will not wobble or be washed away by water pressure, etc., so it can be used with confidence. .

The material of the partition plate according to the present invention is preferably synthetic resin from the viewpoint of durability, but it may also be made of wood.
